Hypnos

Hypnos is the divine personification of sleep and a loyal subordinate to Hades, the Emperor of Darkness. He is the twin brother of Thanatos, the god of death, and holds significant power within the Underworld. Driven by his allegiance to Hades, he serves as an adversary to Athena, the protector goddess of Earth, representing the conflict between the realms of slumber and divine guardianship.
